[0008]The present disclosure provides methods for the treatment and/or prevention of a metabolic disorder. In one aspect, the present disclosure provides a method of treating or preventing a metabolic disorder in a subject, wherein the disorder is induced by obesity, the method comprising reducing the activity of CaMKII, thereby treating or preventing the disorder. In one embodiment, the disorder is selected from the group consisting of Type 1 diabetes, Type 2 diabetes, insulin resistance and metabolic syndrome. In another embodiment, the treating or preventing affects glycogenolysis or gluconeogenesis in the subject. In one embodiment, the treating or preventing reduces hepatic glucose production, hyperglycemia, fatty liver, insulin resistance, insulin resistance-associated inflammation, insulin resistance-associated dyslipidemia, or any combination thereof, in the subject. In another embodiment, the treating or preventing reduces phosphorylation and/or activation of CaMKII. In one embodiment, the activity of CaMKII is a glucagon-induced activity. In one embodiment, the treating or preventing reduces expression of G6pc and/or Pck1 in a cell of the subject. In another embodiment, the treating or preventing reduces the amount of FoxO1 protein level in the nucleus of a cell of the subject. In another embodiment, the treating or preventing reduces phosphorylation of amino acid S284, S295, S326, S467, S475, S246, S253, S413, or S415, or any combination thereof, of the FoxO1 protein.

Problems solved by technology

Obesity is the leading cause of insulin resistance, metabolic syndrome, and type 2 diabetes (T2D), but therapeutic options are limited due to critical gaps in knowledge of molecular mechanisms linking obesity with the metabolic disturbances of insulin resistance and T2D (Samuel and Shulman, 2012).
Moreover, recent studies have shown that calcium transport back into the ER, mediated by sarcoplasmic/endoplasmic reticulum calcium ATPase (SERCA), is dysfuncti

Regulation of Hepatocyte Glucose Production by a Calcium Sensing Enzyme, CaMKII

[0419]Hepatic glucose production is crucial for glucose homeostasis. Several transcription factors and co-activators have been shown to regulate this process, however, the underlying mechanisms have not been fully elucidated. As described herein, a calcium sensing enzyme, CaMKII, is activated in a calcium- and IP3R-dependent manner by cAMP and glucagon in primary hepatocytes and by glucagon and fasting in vivo. Genetic deficiency or inhibition of CaMKII blocks nuclear translocation of FoxO1, impairs fasting- and glucagon / cAMP-induced glycogenolysis and gluconeogenesis, and lowers blood glucose levels. Conversely, adenoviral expression of constitutively active CaMKII induces genes involved in gluconeogenesis and glycogenolysis, stimulates glucose production both in vitro and in vivo, and raises blood glucose levels. The suppressive effect of CaMKII deficiency on glucose metabolism is abrogated by transduct...

Regulation of Hepatocyte Glucose Production by a Calcium Sensing Enzyme, CaMKII

[0421]Liver is the main organ responsible for maintaining euglycemia under conditions of nutrient deprivation. During the early stages of fasting, liver uses glycogen stores to mobilize glucose (Radziuk and Pye, 2001). As fasting progresses, de novo synthesis of glucose from non-carbohydrate precursors, gluconeogenesis, becomes the main contributor to hepatic glucose production (Klover and Mooney, 2004). Glucose production is also regulated by substrate flux through glycolysis, glycogen synthesis, and glycogenolysis. These changes occur rapidly in response to direct hormonal signaling. In addition, both insulin and glucagon affect transcription of glycogenolytic and gluconeogenic enzymes, glucose-6-phosphatase (G6pc) and phosphoenolpyruvate carboxykinase (Pck1), respectively (Pilkis and Granner, 1992). During fasting, glucagon and its downstream effector, cAMP, induce changes in the subcellular localizati...

Abstract

The present invention relates to methods of treating or preventing a metabolic disorder in a subject, methods of treating or preventing coronary artery disease in a subject with a metabolic disorder, as well as methods of reducing hepatic glucose production in a subject. Such methods include, but are not limited to, the administration to the subject of inhibitors or activators of CaMKII, IP3Rs, calcineurin, p38, MK2/3, HDAC4, Dach1, Dach2, or any combination thereof. The invention also provides methods of identifying a compound that inhibits the activity of CaMKII, IP3Rs, calcineurin, p38, MK2/3, HDAC4, Dach1 or Dach2, or reduces the activity and/or activation of CaMKII, IP3Rs, calcineurin, p38, MK2/3, HDAC4, Dach1 or Dach, or activates CaMKII, IP3Rs, calcineurin, p38, MK2/3, HDAC4, Dach1 or Dach2.
